Wrap each ear of corn in foil. Grill for 15 minutes, rolling the corn occasionally so all sides are cooked. Carefully remove the corn from the foil and set aside until cool enough to handle, about 10 minutes.

Using a serrated knife, remove the grilled corn kernels from the cobs. To do this, stand each ear on its wide end, then saw the knife down the length of the cob. Set aside.

Meanwhile, bring a large saucepan of lightly salted water to a boil. Add the edamame and cook until tender, about 5 minutes, or according to package directions. Drain and set aside.

In a large nonstick skillet over medium, heat the oil. Add the bell pepper, onion and shallot. Saute until the vegetables begin to soften, about 2 to 3 minutes.

Stir in the grilled corn kernels and edamame. Saute for 5 minutes. Remove the skillet from the heat, then stir in the vinegar. Season with salt and pepper. Serve sprinkled with chives, if desired.
